That's always my problem when I look at lisp for game programming. If I say "I want to write a standalone 3D iPhone game using C#", there are plenty of sites that'll show me exactly what tools are out there, how they work together, and how to write/debug/package a complete game.
With Lisp, I often end up in the weeds looking at tools and tech that may or may not still be supported. I have a hard time figuring out a well-established set of tools that'll get me a first-class playable game in Lisp.
If anything I'm going to watch this game jam just to see what everyone's using and how good the results look.
